Be it known that I, SECONDO GILETTI, a citizen of the United States, residing. at East Oakland, in the county of Alameda and State of California, have invented new i and useful Improvements in Building (Jon 1 struction',- of which the following is a specification. v

This invention relates toibiiilding construction and particularly toa method of fwallsja-nd partitions in sanitary, reinforced f concrete bl11l(.l1I1gS.-

The 0131661; of the present invention isto 'rovide a device, and method for the con ,struction ofsmooth, finished surfaced walls, partitions, ceilings and other structural elementsm buildings; to provide means Where'- by a complete buildingmay be erected in a fully finishedcondition with the exception of the doors and windows; andY'to provide a method .of producing; a substantially firev proof, monolithic structure at an expense dering the walls or structural elements air much less than at present necessary by making a matrix with asmooth" finished interior, and afterward filling the chamber of the matrix and providing means for renand. water-proof.

It is also a purpose of the present invention to evolve a method in the construction of buildings whereby the use of expensive and labor requiring devices may be eliminated, and the erection of the building continued by theuse. of a simple pumping apparatus whereby the material of' which the structure is to be composed is delivered into the chambers of, the matrix; and also to provide a matrix for building construction having a smooth interior surface, which matrix comprises a number of' complemens tary, cooperative, removable sections adapted to be assembled in the process of erection and permit the completion of successive stories of the building by regular stages.

The invention consists of'the parts and the construction and combination of' parts,

as hereinafter 'more fully described, and

claimed, having reference tojthe accompanying drawings, in which; I s Figure 1 ma perspective view of awportion of the apparatus. F 1g; 2 IS a transverse vertical section of a wall and the molding o1 framing matrix. Fig.8 is a horizontal seetional view of a removable support 15, shoW- ing anexterior shell. s In the present invention I have shown an embodiment comprising a number of wooden frames o-r sections, which may substantially the height of the wall of a. room and which sections may be of such width as to make the same conveniently portable and movable by an. individual. These Wall sections, as 2', are erected vertically upon a foot mold board framing section, as 3, having the contour or face 4 of appropriate cross sectional outline; and uponthe-i upper end .of-the' wall framing sections 2, when the latter have been assembled edge to edge,

there is placed a longitudinal cove forming member 5 of suitable exterior, contour and length. After the several vertical wall or partition forming-sections 2 have been assembled and the cove forming member 7 5 positioned, a plurality of" ceiling' forming sections 6- are lifted into position and keyed therein by means. of a number of removable insert or spacer keys 7 adapted to be supported upon the upper horizontal'plate 8 of the several vertical sections 2.

The several mold forming sections 2', 5 and 6' are provided upon theirm'atrix form ing surfaces with a suitable sheeting 9 which maybe of metal many other appropriate material, which material is permanently attacheol to its relative section, and when the. several sect ons have been positioned, there is presented a continuous, smooth, finished surface", against which may contact asuitable plastic, self-hardening material, as 10, which forms the permanent walls or structural elements ofthe buildingbeingerected.

In order to form a complete matrix for thereception of the plastic filling 10, there is suitably spaced from: the first section of assembled meld" forming sections another set or series of sections which may be of such contour as is requisite for the formation of the desired face of thewa-ll'; such, for in stance, as is shown-on the outersid'e of the filling 10 in Fig; 2', which represents the outside surface of a wall of abuilding In practicingmy method of construction,

' I assemble the several mold forming sections of the desired face or outline as are requisite for thevformation of any given time as the building progresses; thus a complete matrix is formed for the first story of a building, by erecting such necessary sections 2, 5 and Gas go to form the interior finished wall of a given room; the

necessary openings of this room being pro vided by correspondingly formed mold sections. The exterior of the first story of the building is provided for by the erection of vertical mold sections 11 of suitable width and height and when these several inner and outer sections have been assembled there is formed between them a space of the width desired in the thickness of the given wall. \Vhen the outside wall is being molded, it is frequently desirable to protect the interior thereof against the transmission of moisture and cold air from the outside of the building, and this is accomplished by erecting in the matrix chamber between the sections a plurality of core shells 13 of suitable length and cross-sectional area and spaced from each other a suitable distance for the provision of binding webs, as 14, between the adjacent vertical cores 13. I have found that a' very practical, economical waterproofing core shell can be provided by the use of tar paper or other suitable material of suitable thickness and this is particularly adaptable for this purpose, as there is a close adhesion between the tarred shell or core 13 and the plastic material, as the latter is filled into the matrix chamber. Since these flexible, pliable core forming shells 13 have not inherent stiffness or rigidity sufficient to support the load of the-filling material 10 as the latter is turned into the matrix, the core shells 13 are reinforced or supported during the process of construction by removable supports 15,-which may be made of wood or other appropriate material and which are indented or corrugated on their exterior surfaces. These supporting devices are adapted to be removedfrom the hardened walls or partitions of the building as soon as the filling 10 has set sufficiently. Suit-able reinforcing steel rods 16 may be introduced throughout the matrix chamber during the erection of the sections, thereby reinforcing the completed hardened walls of the building. After the plastic filling has solidified and hardened, the key or retaining member 7 is Withdrawn from above the shelf 8 of the vertical sections 2, thus permitting the several ceiling sections 6 to be lowered and removed from the upper portion of the assembled frames, after which the cove forming members 5 are withdrawn and then the sevmatrix forming sections with a smooth sheet lining of appropriate material is to insure that the hardened structural members of the building such as walls and partitions, etc., will have a smooth, finished surface and require no further treatment or coating; these being sufliciently dressed or finished to present a fine appearance.

Having erected the sections to form a matrix in which may be molded the first story of the building and pumping or otherwise suitably discharging a plastic filling material into the chamber of the matrix, this is allowed to solidify and the several mold sections dismantled and re-assembled on the floor above after which the filling material is charged into the matrix to form the second story of the building and so on successively for as many floors as there are in 'the finished structure.

It will be seen that by this method and apparatus thin solid or hollow partitions between rooms may be molded and integrally connected with the heavier main walls of the building and the'floors all cast in one continuous monolithic piece with air spaces and dampproofing materials inserted between the outside walls and partitions as necessary, during the erection of the building.

The sheeting which is applied to the several matrix forming sections presents a smooth, continuous substantially seamless surface, against which the filling material rests as it is charged into the erected sectional matrix and when the plastic material has become sufficiently solid, the several sections may be dismantled, as hereinbeforeexplained, leaving a smooth, finishedsurface requiring no finishing coats; and such ornainent'ations as are desired may be obtained at window and door openings by so designing a cross-sectional area or contour of the molding sections as to produce a finished cast as desired.

By this method of construction a fireproof and moisture-proof building can be erected at a cost not to exceed that of a frame build ing of similar design and size. The material of which the buildingis corgstruc tedran be readily pumped from the lower floors "to the floors in course of construction, thereby avoiding the use of hoisting machinery, wheel-barrows or other expensive apparatus for the placing of the plastic material in the matrix, and by this system very thin walls can be constructed and the several demou'ntable sections of which the mold is formed can be used repeatedly throughout the same building, thus greatly reducing the cost of the temporary work now required in the erection of concrete structures.

As it is desirable to render the intersecting I pending bead along'its lower edge, as at 3,

so as to mold a floor cove 3 The depression .Oneof the important features of this invention is the use and method or use of the tar paper or equivalent cores 13, and the means of supporting these cores against collapse by the use of removable, corrugated core supports 15. It is important that t-lie ,flues which are thus formed in the walls after the core supports 15 are removed,

should be waterproof and with the purpose and function of using tar paper or the like as a sheathing-to the walls of the fines thus formed in the concrete. These tar paper or equivalent tubes, when putin, are sealed so as to be watertight.

gated'vertic-al edges, as shown, can be made cheaply and in-one piece, and a' single core support.- will do for an entire story in a building. They are easily removed, because the narrow lines of contact between the apices of the support and the paper confer a minimum degree of hold on the paper, as

The removable core supports 15, by making them with corrucompared with the cementitious bond be- .tween the paper and core.

fliaving thusdescribed' my invention, what I cla'iin and desire to secure by Letters Pat-.-

An improved building construction, comprising VerticaI wall-forming frame sections and means for holding them in position, vertical core shells positioned between the wallforming sections, said core shells being formed oftar-paper or like water-proof material having little inherent rigidity, and core supports removably fitting within the core shells and-adapted to support thewalls oft-he same against the pressure of, the filling material when. introduced around the core shells, said corersnpports having corrugations, the apices of which form narrow lines ofcontact with the core-shells.
